- Baseline Question: Calculate the pH of a 5.6x10-9M HCl aqueous solution. ANS: pH=6.99 Commentary: Since I know HCl is a strong acid and ionization is 100%, I thought I could find pH as -log(5.6x10-9), however my teacher said that was incorrect . She did a Kw=[OH-][H3O+] to find x. Use image below to see my work. The answer to the question is pH= 6.99. Actual Question:I want to know why we had to do an ICE table and find "x" (another H3O concentration) instead of -log(5.6x10-9).arrow_forwardNaOH is a strong base at 0.0126M concentration. (Show Computation & Highlight Answer) a. What is its [OH-]? b. What is its [H+]? c. What is the pH of the 0.0126M NaOH solution?arrow_forwardFor a weak acid, HA, with Ka = 7.51x10-3, what ratio of [A-] to [HA] is required to produce a pH of 3.897? Answer:arrow_forward
